Without spending a penny, you can completely eliminate the black flies in 2 days. These 4 tricks are amazing!

Seduction

As the name suggests, it means putting some special things around the flower pots to attract and stick the small black flies.

1. Yellow insect trap with special smell

Use a small stick to fix the insect trap board and hang it slightly above the plant. Too high or too low will affect the trapping effect.

Note that the sticking board should be replaced when the insect-stained area reaches 60%.

2. A small basin of soapy water or sugar water

Sugar water will stick to the black flies, and soap contains fatty acids, which will turn into a natural wax coating when broken down. The black flies will become dehydrated and die if they get stuck in it.

Dissolve the soap in water until the pH reaches 1-2 (can be tested with pH paper). Be sure to use soft water such as rainwater, cold boiled water, etc. to dissolve it. You can also add a small amount of sugar water to the soapy water.

Isolation Law

The humidity and temperature of the soil are conducive to the reproduction and growth of black insect eggs, so covering the surface of the potting soil with a layer of dry sand and stone soil is also helpful in eliminating the small black flies.

Of course, isolation requires more than just soil. You also need to remember to get some sun exposure and keep the air ventilated.

Spraying

Use 3000 times diluted acetamiprid or 1000 times diluted potassium permanganate for spraying, spray once every five days or so, and after three or four times, the adults and larvae can be effectively killed.

Spraying pesticides is more thorough in killing insects, but it is risky, so flower lovers should be careful when using it.

How to Make Your Own Pest Control

Many things in our daily life have bactericidal effects, which are not only environmentally friendly, but also effective in eliminating small black flies.

1. Tobacco soaked in water for spraying

The nicotine in tobacco is effective in killing insects. Take a few cigarettes, extract about 20g of tobacco shreds, add 500ml of water and soak for 24 hours, then spray the filtered liquid on the leaves, soil and around the bottom of the pot.

2. Use mosquito coils to kill insects

Mosquito coils contain chlorpyrifos, which can effectively kill insects.

Cover the flower plants with plastic film, place them in a small room, light mosquito coils, and fumigate for a few minutes to effectively remove small black flies; soak the mosquito coils directly in water and pour them into the potting soil to kill larvae and eggs.

3. Garlic soaked in water for spraying

Garlic has a strong bactericidal effect. Crush a head of garlic, pour in half a liter of water, soak it for an hour, and then spray it on the flowers and leaves to effectively kill insects.
